Master’s Challenge [Mf] [Orgasm Denial] [punishment] [CNC elements]

It is the twelfth day of the 8th month of denial for Lisa. This was Master’s challenge: an entire year of constant teasing without orgasms while diligently serving Master’s every need. Good girls knew that Master’s request is her law – and Lisa was a good girl. Now, after eight months of constant, agonizing orgasm denial, Lisa certainly had more than a tinge of regret and frustration about her situation.

She tugged at the thick leather cuffs with futility, all the while knowing that they won’t come off until Master gives the o-k. Whenever the cuffs are locked-on, Master always had something special in store for her. Or, more accurately, it was something special for him and him alone. The *special* that she wanted he would not give: she desperately needed to cum.

Feeling the vibrations on her clit and getting lost in her thoughts, Lisa let out a small moan into her gag. Then, realizing her mistake, she bit down on the gag and braced for the punishment. Her eyes widened in fear and she counted in her mind in-between each timid breath: “One. Two. Three.” A sharp shock coursed through her nipples and her back arched from the pain. For a second, she seemed to levitate off the bed like a startled cat. This time, Lisa did not make a sound.

At the beginning of the challenge, Master had installed a voice recognition module into their play bed. Whenever the cuffs are locked on, Lisa was to be absolutely quiet no matter how intense the stimulation gets. Whenever she made a sound, she was punished with a long and painful shock to her sensitive nipples followed by a round of edging. “The gag is not there to keep you quiet,” Master had said, “it’s there so you have something to bite onto when you get punished.”

Then, as scheduled, Lisa winced as the vibration at her clit increased in intensity. She jerked her hands back against the cuffs, as the dildo inside of her pussy also began vibrating. She hated this goddamned chastity belt. She hated how it was programmed to deliver random vibrations to her sensitive parts to keep her constantly horny. Most of all, she hated how it could detect her heart rate or whatnot, and deliver the perfect edging every time. Master, the tech founder, had more than enough resources and knowhow to give poor Lisa everything she could possibly want – except an orgasm, of course.

Lisa bit down on her gag as waves of vibrations coursed through her body. She could feel the orgasm building, and she barely noticed that her wetness soaked through the belt and onto the white sheets below. Then, as the crest of pleasure was about to break, the vibrations stopped.

*AHHHH*. Lisa breathed sullenly and silently into her gag. She was keenly aware of future punishments…

She barely had time to catch her breath before she noticed her Master. He was a man of a muscular build, and wore a simple white shirt with slacks. Master leaned against the doorway. He held a thumb-sized keyfob in one hand and a devious smile on his face.

“Want more of this, babygirl?” Master asked, holding up the keyfob.

Master tapped on a part of the keyfob and Lisa felt a pulse of pleasure radiate from her clit. She nodded her head eagerly, and tried to put on her best puppy-face.

“I asked you a question.” Master said sternly, with a smile. “Say yes if you want to cum.”

She glared at him, and tilted her head to gesture to the cuffs.

Master pretended to not notice. “You don’t want to cum. Okay. One more edge then.” He said. He proceeded to press a quick succession of buttons on the keyfob to send Lisa’s belt whirring again with movement.

Lisa, still lying down and cuffed spread-eagle, breathed heavily into her gag. It was the only sound she could make without triggering the punishment module. She huffed into the gag and contorted her bound body in response to the waves of pleasure, as Master came up to the bed and sat beside her.

He stroked her hair. “There’s my good girl, doing her favourite thing in the world: not cumming.”

Lisa was feeling breathless. The combination of Master’s touch and the relentless vibration at her pussy was almost too much for her to handle. She longed for the heaven of climax, to have Master’s hard thick cock pound her until she submits fully in body, and in mind.

Then, as it always does, the vibrations stopped without warning. Lisa had not noticed that Master was now straddling her. Pants off now, Master’s underwear had a large bulge. Lisa breathed into the gag. “God, I’m so fucking horny” She thought. “Just give me that dick.” Lisa hasn’t had the privilege of Master’s cock in her pussy since the beginning of the challenge, 8 months ago. Just the thought of it would have made her sopping wet, if she wasn’t already.

Master had a predatory gaze that unnerved Lisa. He grabbed Lisa by the chin and pinned her head down to one side. He leaned against her ear and growled into it. “Enough of this. It’s time I use you.” He said. “Open up,” he commanded, as he reached under her head and unbuckled the gag and pulled the ball out with one hand. With his other hand, Master shoved his cock into Lisa’s mouth.

She felt the tip of Master’s cock ram the back of her throat, and in the process of gagging and in the heat of the moment, she let out a gurgle and moan. One. Two. Three. A long and painful shock lit her nipples on fire and she writhed into Master’s cock. His length and girth made her gurgle once more. Between screaming, which would have resulted in a longer shock, and clamping down on Master’s cock, which would have resulted in a lifetime’s worth of punishment, Lisa made the wiser choice.

“Ahhh-” She screamed. It was quickly turned into a “ -mmmmf” as Master buried his cock and balls deep in her face.

The vibration from the previous punishment cycle kicked in. It was followed by the new shock of a higher intensity for her most recent transgression. Once again, Lisa buckled in pain and tried to pull her bound hands towards her body. Of course the cuffs didn’t budge. All the while Master pinned her down and continued to violate her throat. His cock was twitching now. He had grabbed onto her hair and was ramming himself into her mouth.

Wham. Wham. Faster. Wham.

Then, with a final stroke, Master grabbed Lisa’s head with both hands and shoved his cock in her mouth. He shot hot strands of cum into her throat, and she sucked on it hungrily, not wanting to lose a single drop. Good girls never spill Master’s cum.

When he was done, Master did not let go of her head. He kept his huge and twitching cock inside of her mouth and tightened his grip on the back of her head. A few seconds passed, and though Lisa was distracted by the intense edging punishment at her pussy and clit, she felt a rising sense of panic as Master’s cock made it impossible to breathe. Each second now was accompanied by an increase in vibrations and less air. She tried to rattle her hands and feet but to no avail.

As the vibrations hammered her pussy in impossible ways, and Master’s thick and twitching cock filled her throat, Lisa finally couldn’t take it anymore. “Mmmmmfff.” she moaned and groaned into his cock. Master let go of some of the pressure, but kept himself in her mouth. She moaned again, this time, shaking her head.

Satisfied that his denial slut had earned herself two extra punishments, Master pulled himself out of her mouth, before putting the gag back in Lisa’s mouth with a swift motion. *Click*, went the buckle of the gag. Lisa found herself once again gagged, edged to the point of climax, with Master’s cock resting on her face. She looked at him dreamily, but with a certain urgency.

Her serenity was broken by two shocks to her nipples in quick succession. Each more painful than the last. Of course, she moaned and screamed when the cuffs were on – and that meant she would get punished. Soon after, the vibrations kicked into an even higher gear. Lisa was now gyrating her hips back and forth, hoping to make enough contact with the vibrations to cum. Of course, she knew that the belt wouldn’t let her.

When the second peak had hit her and abruptly stopped right before she could orgasm, Lisa had finally had enough.

“Pwhhhese,” she breathed into the gag.

Master looked over at her. He was now sitting at the edge of the bed flipping through his phone. Maybe he was on reddit, who knows.

One. Two. Three.

Another shock sent her body arching.

“No! Please, Sir, no more.” Lisa tried to say. It came out barely intelligible in-between the gag, the shock, and the vibrations.

Master put his finger against his lip and gestured the “shhh”. One. Two. Three. Shock number five.

“Buh- Banana!” Lisa screamed into the gag with enough intensity to lift the gag slightly, making it the most intelligible word she had said all day. It also happened to be their safeword.

Master put his finger on the keyfob and pressed on it lightly. The vibrations came to a total stop. Then he unbuckled Lisa’s gag once more, but left her hands shackled to the corners of the bed.

“You sure, babygirl?” He asked.

“Yeah.” Lisa breathed a sign. “I mean, yes, sir.”

“You know what happens when you use the safeword, don’t you?” Master asked, wanting to make sure. Lisa nodded.

Lisa knew that the safeword meant the end of Master’s challenge. She had failed his challenge, and now there would be consequences. The most immediate consequence: the shocks will stop, and she gets to cum for the first time in eight months. The more long term consequence – the one she’s too fucking horny to even consider – is that she has just permanently surrendered her orgasms to Master. No more teasing, but also no more cumming unless it was at Master’s pleasure. Now, her only job is to give pleasure and to serve Master. Lisa was now a denial slut for life, her orgasms at the mercy of Master, forever. Lisa shuddered in pleasure at that thought.

“I’ll turn the vibrations to max now, and let you cum as many times as you can in 10 minutes.” Master said. He twirled the keyfob in his hands and pressed a button on the back. “

“Then, after you’re done cumming, I’m going to take the vibrating toys out of your belt and lock it back on. That belt is your home now, and you’re never gonna cum again.” He said.

He looked over at Lisa, who was writhing in bed in a pool of orgasmic bliss. Master wasn’t sure if his babygirl had heard him, but that doesn’t matter now.
Master leaned over to kiss Lisa on the forehead, before prying open her jaws to put the gag back in.
